Gigaopto’s GTS-B23B1-10DC SFP28 optical transceivers are designed for bi-directional serial optical data communications such as Ethernet/eCPRI/CPRI links up to 25.78 Gb/s data rate and up to 10km link length. They are compliant to SFF-8472 Rev 12.2, and compatible with SFF-8432 and applicable portions of SFF-8431 Rev. 3.0.

The transmitter section uses a 1270nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses a 1330nm integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a rate selection clock data recovery (CDR) IC.

The optical transceiver is compliant per the RoHS Directive 2011/65/EU.

This bidirectional unit must be used with another transceiver or network appliance of complementing wavelengths (our model P/N GTS-B32B1-10DC).
